Title: Method of forming a continuous metal coating on rigid metal sections and apparatus therefor
IPC: C23C2/38
Filed: 1976-05-28
Abstract: According to this process for galvanisation of straight metal sections, the articles to be treated (15), heated at least to the temperature of the molten coating metal, are passed through two leakproof tubular chambers (6 and 3). These chambers are situated on either side of a closed galvanising vessel (5) fed with molten metal by a pump (11) up to the immersion level of the articles to be treated (15), in a neutral or reducing atmosphere and at a pressure close to atmospheric pressure. The emergence of the treated articles from the galvanising vessel (5) takes place in a neutral or reducing atmosphere, through coaxial frustoconical nozzles (20) level with a funnel (8) for returning the leakages of molten metal. A closed galvanising vessel (5) of considerably reduced volume can thus be employed. <IMAGE>

Abstract: 1,013,852. Photographic materials. ILFORD Ltd. May 13,1964 [June 7, 1963], No. 22804/63. Heading G2C. A photographic material comprises a layer containing a silver salt which is developable or may be rendered developable and a yellow Formazan dye which has the characteristic open-chain chromophoric structure:- On developing the material with an N: N-disubstituted-f-phenylene diamine type colour developer, the Formazan dye is decolourized in the region of developed silver. Integral masks for correcting unwanted absorption in magenta or cyan colour images which, apart from their main absorption bands, absorb undersirably in the blue band are made when a silver salt emulsion is developed which contains a yellow Formazan dye absorbing in the blue band to an extent substantially equal to the undesired absorption, the magenta or cyanproducing colour formers being in the emulsion or in the colour developer. Integral masks may also be made when the Formazan dye is in an additional silver salt emulsion layer containing no colour former but which is sensitized to the same waveband as the silver salt emulsion layer containing the colour former. Multilayer material having red, green and blue-sensitized layers with colour formers yielding complementary colours and containing a yellow Formazan dye in the red or green-sensitive layer is described. Examples are given of the correction of single-colour magenta and cyan images, including (4) the correction of a cyan image by incorporating in the redsensitized emulsion a cyan-forming coupler and a yellow Formazan dye to correct for blue obsorption, and then treating the image with a cupric salt solution to correct for green.

Title: Electronic system for locating
IPC: G08B3/10
Filed: 1973-05-14
Abstract: 1399313 Electronic locating system RECOGNITION DEVICES Inc 14 May 1973 22891/73 Heading G4H [Also in Division H4] A locating system (e.g. in a building) comprises means 13 in a central console 10 for transmitting a VHF or UHF signal 19 identifying a person being sought, portable units 20 comprising means 25 for generating an ultrasonic signal in response to reception of a signal whose frequency corresponds to the carrier of the unit, stations 30 in fixed locations having means responsive to an ultrasonic signal generated by a nearby unit to generate in turn a signal 37 having a frequency identifying the station, and means 47-51 in the console responsive to this signal to indicate the station 30 and hence the location of the person being sought. The frequency 19 to be transmitted is selected by depressing a key 17 on the console. Each unit 20 includes a button 26 which the person carrying the unit may depress to actuate an audible or visual alarm on the console. The console and each station 30 may be provided with ring-counter actuated reed switch networks for scanning the locations of all the persons in the building (Fig. 2, not shown). The system may make use of the ordinary building electricity supply network, and stations 30 may be arranged to transmit signals of different polarities as well as of different frequencies (Fig. 3, not shown). One transmitter may be shared among a group of stations 30 (Fig. 5, not shown), the central console then incorporating means to accept only the first frequency received from stations of the group, which identifies the station of the group nearest the person sought. The above system may be adapted to cause a telephone 115, Fig. 4, to ring near the person being sought. An access code and a code identifying the person to be contacted are dialled on a phone 111 connected to a switching network 101 (e.g. a private branch exchange). An access network 103 thereby signals a decoder 105 (which causes transmitter 13 to generate a signal of there. quired frequency) and also opens a gate 109 so that the incoming location-identifying signal can pass from receiver 47 to a decoder 107. Decoder 107 translates the received A.C. signal into one recognizable by network 101 as being directed to a particular extension 115, which is thus caused to ring, after which a network 120 blocks gate 109 and turns off decoder 107.

Mixtures comprising components having intersecting temperature-retention index curves are separated by elution gas chromatography by flowing the mixture in one direction through the column at a temperature below the point of intersection, and then in the other direction at a temperature above the point of intersection. As shown, the mixture is injected at 12 into column 10 to which carrier gas is fed from source 18 by valve 26 and line 28, the column being contained in chamber 40 and heated to a temperature below that of the intersection of the retention index curves of the components of the mixture by heater 41. When the front of the fastest travelling component is detected by detector 16, thermostatically controlled heater 42 is switched on to raise the temperature above the intersection point and valve 26 is switched to reverse the carrier gas flow so that it passes by line 30 to column 10. When the first component reaches detector 14, heater 42 is switched off and the gas flow direction controlled by valve 26 reversed once again. The cycles are continued until the desired degree of separation has been achieved, when the fractions are removed through exhaust 36. In Fig. 4 (not shown), the mixture is fed continuously to the midpoint of column 10, and traps are provided in lines 28, 30 to enable continuous separation. A block diagram of a suitable automatic control circuit 34 is provided.
